The label of a certain brand of 1-ounce chocolate chip cookies states that the cookies contain 110 calories. To make sure that the claim is not exceeded, a quality engineer routinely samples their cookies and checks the calorie content. A random sample of 15 1-ounce chocolate chip cookies resulted in the following calorie amounts:

100, 125, 150, 160, 185, 125, 155, 145, 160, 100, 150, 140, 135, 120, 110

We want to know if, at the α = 0.05 level, there is sufficient evidence to conclude that the average calorie content of 1-ounce chocolate chip cookies produced by this brand is greater than 110 calories.
